           Summary: Hotplug doesn't work with SAS1064
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.27-rc6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: SCSI
        AssignedTo: [email protected]
        ReportedBy: [email protected]

Latest working kernel version: 2.6.20
Earliest failing kernel version: 2.6.22
Hardware Environment: Any Intel-powered server with SAS1064 PCI-X SAS controller
Problem Description: I have linux-box with SAS1064 PCI-X SAS Controller, and I'm experiencing problems with hotswapping. When I detach disk from system, replace it with another one, and trying to attach it again, nothing happens. After reboot, it's OK - I have this disk attached and functioning. Interesting, that if I try to attach old disk just after detaching it's OK too. I've tried following Vanilla kernel builds from linux git tree: 2.6.20, 2.6.22, 2.6.24, 2.6.26, 2.6.27-rc6 and it's worked only with 2.6.20. So, I tried to bisect buggy commit between 2.6.20 and 2.6.22 versions.
Here is bad commit: df9e062ad994c4db683377b108c0dbed4690e4b0

Steps to reproduce:
- detach disk with:

# echo "scsi remove-single-device x y z k" > /proc/scsi/scsi
- physically remove it and insert another one;
- try to attach disk with:
# echo "scsi add-single-device x y z k" > /proc/scsi/scsi
or with
echo "- - -" > /sys/class/scsi_host/hostN/scan

In reply to Andrew Morton

Can I request progress status of this bug? I have more than 100 boxes with this controller, and I can't change faulty hard drives without reboot. And I can't use 2.6.20 on them too. :(
